Branwen made me want to slap her silly at first, at the end of the last book she was prepared to get down to the job, at the beginning of this one she turned whiny and annoying. I'm not sure that my initial feelings towards her changed throughout, I stopped rooting for her and just wanted her to get on with it.
Branwen gains allies and finds out who some of her enemies are. It's interesting but nothing stood out for me or made me want to read more.
